FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 395,205, dated December25, 1888.

Application filed May 27, 1884. Serial No. 132,960. (No model.)

To @ZZ whoml it may concern:

Be it known that I, THOMAS M. BEER, of Ashland, in the county of Ashlandand State of Ohio, have invented new and useful Improvements inForce-Pumps, of which the following is a description.

The abovesaid improvement relates to that class of pumps used in drillor drive wells, and which is fully described in the followingspeciiication, and shown in the accompanying drawings, making a part ofthe same, in whichM Figure l represents a transverse vertical section ofthe improved pump. Fig. 2 is an enlarged horizontal section through theline Fig. 3 is an enlarged detached section, a portion of which is shownas broken away.

Like letters ot' reference refer to like parts in the several views.

The pump shown in the (hawings is provided with two cylinders, A and B,connected to each other by a pipe, C, of any desirable length.

duction-pipe ln said cylinder B is a piston, F, provided with valves ao, and which is operated by the handle G, to which it is the uppercylinder will follow the lower one connected by the valve-rod H, passingupward through the cylinder A 'to the handle, as shown in the drawings.

The cylinder A alluded to consists of a shell having an interior pipe,l, forming an integral part tllereof-that is to say, the cylinder andthe pipe l are cast in one piece-but which, however, may consist ot' twoseparate parts and united to each other in any appropriate manner. lt ispreferred to have the cylinder and pipe in one piece. lt will beobserved in the drawings that the pipe l has an eccentric. relation tothe cylinder, thereby forming a cresceixt-shape passage, J, Fig. 2,between the interior side ot the cylinder and the pipe. An openeommunication exists between the passage J' and the pipe, as seen at Kin Figs. l and 23, formed by making the pipe I shorter than thecylinder, so that a direct open relation exists between the lowercylinder, B, and the upper one and with the passage J, as indicated bythe arrows. Said passage J extends to the discharging-pipe L,

In the lower end of the cylinder B l is a valve, D, for opening andclosing the inand is connected thereto in any suitable way.

In this class of pumps as ordinarily constructed the cylinder A and thedischargingpipe corresponding to the passage J, above described, are twoseparate and distinct parts. The discharging-pipe is on the outside ofthe cylinder and connected thereto by an elbow and coupling. Theaddition of this pipe to the side of the cylinder prevents the saidcylinder from following the lower one, B, into the bore of the well.Hence an enlargement of the bore at the surface of the ground must bemade to receive the cylinder and the side pipe attached thereto. Thisenlarging of the bore or well for the purpose specified is attendedoften with much trouble and no little expense, as the enlargementrequires curbing and a platform laid over it for protection.Furthermore, making the cylinder and the discharging-pipe in twoseparate parts adds to the expense oi' the pump in the manufacturethereof.

The objections above mentioned are avoided in making the cylinder andthe dischargingpassage J as herein shown and described, the two being ofno larger diameter through the line 0c az than the lower cylinder, B ghence into the bore of the well, thereby avoiding any enlargement of thebore for its admission therein, and 'for the reason that the cylinder'and the pipe I, `forming the passage J, are of one piece the pump ismore simple `in structu re and :more readily and easily placed inposition Vfor practical use.

The operation of the improved pump is substantially the same as thosehaving the cylinder and the discharging-pipe in separate parts, andwhich is brieii y thus: The two cylinders A and B are inserted in thebore of the well. The passage J, as aforesaid, is connected to thediscl'rarging-pipe L, projecting' Aabove the ground M, and is held inposition by the brace N. On lifting the piston F to the position shownin the drawings the valve D opens and the water Hows from the well intothe cylinder B. A downward stroke oi' the piston closes the valve D andforces the water through the valves a a into the pipe C, thence into thepipe l, and a portion of which IOO is forced up the passage J by thepiston O in the pipe I of the cylinder, as the said piston descends conjointly with the piston l?. The Water forced up the passage J' Iillsalso the discharging' -pipe L and .iiows therefrom through the nozzle P.A now upward stroke of the piston opens the valve l) and closes theValves a a. This upward action of the piston F continues the flow olwater up the passage J, the water being' forced from the pipe I and thepipe C, which have a much larger holding' capacity than the passage .Iand the discharging-pipe, so that t-he excess of -water in the pipe I,is forced up the passage J and pipe L by the upward action ot' thepiston F, thereby causingr a continuous ['low 0f water from the nozzle Pwhile working the pump.

In the ordinary pump i'or drive-wells there is an air-chamber at theupper end ot' the side pipe, a continuation oi which extends down aroundthe discharging-pipe to facilitate the upward flow of water.

In this improved pump the air-chamber is dispensed. with, but anair-space is retained around the discharging-pipe, as shown at Q in Fig.l, which produces the same result.

Vhat I claim my invention, and desire to secure by Letters Patent, is-

ton-chamber and piston therein, an upper cylinder of even exteriordiameter with the lower cylinder and located above the same, aconnecting-pipe between the two, a piston-chamameter than the lowerchamber and arranged in an eccentric position therein, thus leaving oneof the walls of the cylinderthicker than the other, and adischarge-passage formed in` THOMAS M. BEER.
